Abstract (en)

[origin: WO2008066548A1] A representative digital circuit of the invention has an on-chip, non- volatile memory, to which chip-specific speed-binning data that characterize performance of the digital circuit are written during production testing. During normal operation, the power controller that controls power-supply signals applied to the digital circuit reads the speed-binning data from the on-chip memory for use as input parameters for dynamic supply-voltage scaling, dynamic clock scaling, and/or adaptive power control that optimize (e.g., minimize) power consumption in the digital circuit. Advantageously over the prior art, the accuracy and efficiency of dynamic and/or adaptive power control arc improved because the chip-specific speed-binning data enable the power controller to better customize the power-management algorithm for the given digital circuit.
